T afZZ whom may concern.-

Beit known that I, NICOLAS BnooNoirPo- LITO, a citizen of the United States, and residing in the city of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Filters and Distillers, of which the following is a specilication.

My invention consists in certain new and [o useful improvements in apparatus for the 'liltering and distilling of water. I show com'- bined means for performing both of these operations and automatic means for condensing and cooling the product. I also` provide automatic means for maintaining the proper level of water in the distillingapparatus and" novel construction and arrangement of the various parts of my invention, `as will appear by the accompanying description.

o In the accompanying drawings, Figure 1 is an elevation of my combined filter and distillcr, the ilter-casing being in vertical section and the 'filter stone being partially broken away in similar section for the sake of clearness. Fig. 2 is an inverted plan view of the casing-cover. Fig. 3 is a plan view of the invention; and Fig. 4 1s a vertical section, von an enlarged scale, of the feed-receptacle. The following is a detailed description of 3o the drawings:

1 is the iiIter-casing, formed of copper or other suitable material and preferably of the cylindrical form shown. The capacity of said casing is regulated by the amount of fil- 3 5 tered product desired. 'lhe upper ortion of said casing is preferably contracte conically and provided with annular collar 2 and a plurality of pierced ears 3 3. 4 is the inlet-pipe, communicating with the interior of casing 1 and connected with the service-pipe or other" source of water-supply. 4a is a valve in pipe 4 to control the flow of water through said pi e.

5 is the drain-cock 1n the wall of casing 1, near the bottom thereof, adapted to empty the water from casing 1 when desired.

6 is the cover, preferably cesti of brass or other suitable material and having in its under face the annular groove 7, adapted to receive 5o the annularcollar 2 of casing 1. 8 is an annular gasket, of rubber or other suitable material, seated in said groove 7 and adapted t0 be compressed by the edge of collar 2 to form.

a water-tight joint between the cover 6 and the casing 1. 5 5 9 9 are pierced ears integral with cover 6 and corresponding in number and location with the ears 3 3 of casing' 1. 10 10 are bolts passing through pierced ears 3 and 9, thus holding said cover firmly in place. 6o

11 is a central downwardly-depending projection either integral with cover 6 or attached thereto.

12 is a horizontal passage through the center of cover 6 and having its ends threaded 5 'i to engage pipe ends, to be described.

13 is a vertical passage in cover 6, extending from passage 12 down through projection 11, and 14 14 are one or more ports through the wall of projection 1 1, communicating with 7c passage 13. j

15 15 represent one or more filter-stones, either natural or artiiicial, which are strung on rod 16, whose upper end is secured in the lower extremity of passagelB by .threaded engagement. Said stone or stones are held in place on said rod 16 by means of nut 17, securing in place washer 1S, which also serves to prevent the entrance of water from below into the central bore 19 of the stone or stones 8o 15 15.

20 is an annular gasket, of suitable material, compressed between the top of stone 15 4and the under face of cover 6 and surrounding projection 11, thus preventing the entrance ol unfiltered water from casing 1 through ports 14 14.

l21 21 are gaskets or washers of suitable material interposed between stones 15 15'to prevent the entrance of unfiltered water be- 9o tween the same into the bore 19.

The central bore 19 of the top stone 15 is countersunk or enlarged adjacent to its top to permit free passage of water from said bore 19 around said projection 11 to ports 95 14 14.

23 is a pipe in threaded engagement with one end of passage 12 and provided with a cock 24 for the withdrawal of filtered water thereby. loo

25 is a boiler for distilling the water received from the filtering apparatus above described.

26 is a gas-burner or other means for heating the contents of boiler 25. 27 is the feedlos' receptacle located adjacent to said boiler and end With a cock 36.

connected therewith by feed-pipe 28, leading l from the bottom of said receptacle to a point in the side of boiler at the desired Waterlevel therein.

29 is an overflow-pipe extending up into receptacle 27 to a point slightly above the Water-levelin boiler 25. It is evident that the proper level of Water in boiler 25 will be maintained automatically as long as Water is fed to receptacle 27, the surplus Water not required in boiler 25 being carried off through pipe 29 from receptacle 27.

30 is a-pipe in threaded. engagement with the other end of passage 12 and provided With suitable valve 31 and downwardly-extending outlet 32, by means of Which Water may be admitted to receptacle 27.

33 is the cover of boiler 25, secured thereto" by any convenient means, (notshoWnQ-and 34 is the outlet-hood integral,V with or -attached to said cover. Said hood-is communication with the end of pipe 35 *rhich enters the interior of casing 1j andprhs a condensing-coil about the 'QW-all?Y th'ijeof, emerging therefrom adj acent`to the -bo `om of said casing and, if desired, provi: 'its 37 is a small orifice in hoddA "toip'i the escape of any gas which mayb-ejcarr-l by the steam or vapor arisingfroniiboiler through hood 34 on its Way into' coil 35.

The operation of my improved combined filter and distiller is as followsz'fThe valve 4a is opened to admit Water through pipe 4 under pressure, which pressure. in casing 1 forces the Water contained therein through stones 15 15 into central bore 19, up which around rod 16 it is forced into chamber 22, through ports 14 14, into passage 13, into passage 12, whence it may be drawn for use through cock 24, if desired. If it be desired not only to filter the Water, but also to distill the same, the valve 31 is opened, admitting Water to receptacle 27 through pipe 30 32.

The Water will pass from receptacle 27 to boiler 25, as shown, Where it Will be heated by burner 26 for the generation of steam and vapor, which will pass into hood 34, Where it Will be relieved of any gas contained therein by means of orifice 37. The steam and vapor will then pass into condensing and cooling coil 35 and issue as filtered and distilled Water of perfect purity at the outlet end of said coil 35. It is evident that as long as the gas-burner 26 generates sufficient heat and the valves 4 and 31 and the cock 36 are kept open the Working of my filter and distiller Will be automatic and continuous, a constant stream of product issuing from the outlet end of coil 35.

The advantage of furnishing filtered Water for distillation is that all material held in suspension therein is first filtered out before being admitted to the still or boiler, thus preventing the clogging of the apparatus by the precipitation thereof.'v The capacity` of the filtering or distilling apparatus may be varied according to need. The extreme simplicity and compactness of the device enablesit to be manufactured at small cost and particularly adapts it to domestic use, as the space required for its installation is rela- -tively slight. One or more filter-stones may be used, as desired. I prefer a number of smaller stones attached together rather than one single stone but either construction may be resorted to. If but a small quantity of Water is to pass through the filter, one small stone may be used alone.

To cleanse the filter, all that is required is the removal of bolts 10 '10, which will allow the cover 6 to be lifted off, taking with it the pendant stones 1511-5.

Under usual circumstances the filtered and distilled Water emergesfrom coil 35 at a comparatively loiv`teinperature 5 but-should the Water in leasing l f-a-ilcto-properly cool the condensed Water in coil-35 then drain-cock 5 may be left partially-open, thus more rapidly replacing the Waterstanding in casing 1 with fresh cooler Water from pipe 4.

While I have minutely described the con- A. struction illustrated in the accompanying drawings, I do not limit myself thereby, but claim broadly- 1. In the character of apparatus described., a filter, a distiller adjacent thereto, means for supplying the product of said filter to said distiller and means contained within said filter for condensing and cooling the product of said distiller.

2. In the character of apparatus described, a casing, filtering means contained within said casing, a Water-supply connected with said casing, a distiller adjacent to said casing, means for supplying the product of said filtering means to said distiller and a condensing-coil Within said casing connected with said distiller.
